IMPROVEMENT IN VERTICAL STEAM-ENGINES.

Specification forming part of Letters Patent No. 156,072, dated October20, 1874; application filed May 22, 1873.

.To all whom it may concern:

Be it known that I, THOMAS J. YOUNG, of Philadelphia, Pennsylvania, haveinvented an Improvement in Vertical Steam-Engines, of which thefollowing is a specification:

I have in view two principal objects in the construction of my engine,viz: First, to construct it so that it shall occupy a minimum of spaceas compared with other vertical engines of like power, and shall,therefore, be adapted for use in tug-boats, and in buildings where spaceis a material object; second, to construct it so that the stuffing-boxcan be easily got at for repackin g and repairs and the cross-heads andguides easily removed for repairs Without in any case disturbing thecylinder.

The several working parts of my engine separately considered areconstructed as usual. My invention consists of a combination of theseparts with three (3) columns arranged with the two-fold purpose ofsupporting the cylinder, and inclosin g a triangular space below thecylinder for the piston-rod, cross-head, guides, and connecting-rod. 1

Figures 1 and 2 are, respectively, rear and end elevations of theengine; and Fig. 3, a horizontal section of the same on the line as y ofthe other views.

Referring to the drawings, a is the bedplate; 12 c d, the three columnsemployed to support the cylinder and steam-chest. e f is the cylinderstuffing-box; g, the piston-rod; h, the cross-head; i and j, the guides;k and l, the braces attached to the back columns 0 and d for supportingthe guide j. m is the connectingrod; n, the fly-whe el; 0, the crank;10, the valve-stem, and q the eccentric-rod.

I do not, broadly, claim the provision of three columns instead of twoor four, as, without any peculiarity of arrangement, there would, Iadmit, be neither invention nor merit displayed; but

What I do claim as new, and desire to secure by Letters Patent, is-

In an upright steam'engine, the improved arrangement of parts,comprising the three columns b c 01, standing upon the base a, in therelation of the angles of a triangle, and connected together at theextremities only; the cylinder and valve-chest supported above and uponsaid columns; the transverse bars or braces k 1 connecting the columns 0d; the guides i j attached, respectively, to the column b and bars k l,and the head h, traveling between said guides in the center of the spaceincluded by the three columns, all combined substantially as shown anddescribed, and for the purpose specified.
